I In France September 16, 1936 C1aims. (01. 131-152) The present invention has for its subject a device for ensuring the automatic regulation of the delivery of hydraulic mains.

This device consists of a movable cylindrical 5 valve located in a closed chamber and moving in front of the orifice of the outlet conduit, the movements of the said valve being regulated by a jet, from the supply conduit, acting on a plane surface. This plane surface, in the'form of a disc, and the valve are mounted at opposite ends of an arm capable of oscillating aboiitan axis.

' This axis is at the same time the axis of the cylindrical surface of the valve.v

The single figure in the accompanying draw- 16 ing shows a method of construction of the device according to the invention. Q

The water enters a closed chamber 2 through the supply conduit I. The outflow conduit 3 is also branched from the chamber 2.

In front of the inlet orifice of the conduit 3 is located a valve 4 in the form of a cylindrical sector of which the centre is at 5, which is theaxis of oscillation of the whole device.

The valve 4 is mounted on an arm 6 capable of oscillating about 5. At the opposite end is located a plane surface 1 adapted to receive the jet leaving the pipe I. form of a disc, preferably provided with a rim 8. The outlet end 9 of the pipe l'is shaped in a manner to promote the formation of a jet. It rliiiay be provided with an adjustable needle valve The assembly consisting of the valve 4, the arm 6 and the surface 1 is suitably balanced for any desired value of the jet leaving the pipe I. This balance may be adjusted by means of a counterweight ll.

The lower end of the valve 4 is preferably constructed in the form of a blade I2. I

The operation of the device is as follows.

The jet leaving I impinges upon the surface I and its action tends to apply to this an upward thrust. This thrust is balanced by the weight II in such a manneras to obtain for a given value of the jet a definite position of the valve 4. By reason of its cylindrical shape the valve is not subjected to any force of thrust. There only comes into action the effect of its weight proper.

When the delivery of the pipe I increases, the

power of the jet increases, the thrust on the disc ll becomes predominating and causes the arm 6 to oscillate. The valve 4 thus closes, immediately reducing the delivery of the pipe 3. This action takes place until the delivery has been restored to its normal value. If on the con- This surface I' is in the rim surrounding the trary the delivery of the pipe I is reduced, the

it has been assumed that the chamber 2 is 10 closed, which is the most suitable case in practice, as it supports the load to which the pipes I and 3 are subjected. It may however be open at the top on condition that its height corresponds to the said load. 15

Various modifications may be made in the various parts of the device without departing from the scope of the present'inventlon.
